I'm having a hard time sharing an image from an ImageView from a button, tried several methods, but none worked.

Here is an example of what I want to share: link

I have an array with the path of the images in Drawable

final int[] photos = {
                R.drawable.abrir_a_boca,
                R.drawable.adicao_de_quartos,
                R.drawable.agarrado_firmemente,
                R.drawable.agradeca,
                R.drawable.alfaiate,
                R.drawable.ancora,
}

compartilhar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                shareImage();
            }

            private void shareImage() {

                Intent shareIntent = new Intent();
                shareIntent.setAction(Intent.ACTION_SEND);
                shareIntent.putExtra(Intent.EXTRA_STREAM, "local do arquivo");
                shareIntent.setType("image/jpeg");
                startActivity(shareIntent);
            }

But it never worked, now I do not know if the problem is with my device that is with Cyanogen, because I already saw several solutions to this problem in Stackoverflow, but none worked.

You need to save the image so you can share:

Come on:

Permission:

In your AndroidManifest.xml file add the permission so that we can save the image to the device:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Runtime Permissions:

From Android 6.0 (API level 23), users grant permissions to applications while they are running, not when they are installed.

To do this, add the following code method:

private static final int SOLICITAR_PERMISSAO = 1;
private void checarPermissao(){

    // Verifica  o estado da permissão de WRITE_EXTERNAL_STORAGE
    int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);


    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        // Se for diferente de PERMISSION_GRANTED, então vamos exibir a tela padrão 
        ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, SOLICITAR_PERMISSAO);
    } else {
        // Senão vamos compartilhar a imagem
        sharedImage();
    }
}

Share the image:

Now, let's save and share the image:

   private void sharedImage(){
        // Vamos carregar a imagem em um bitmap
        Bitmap b = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher_round);
        Intent share = new Intent(Intent.ACTION_SEND);
        //setamos o tipo da imagem
        share.setType("image/jpeg");
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        // comprimomos a imagem
        b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        // Gravamos a imagem
        String path = MediaStore.Images.Media.insertImage(getContentResolver(), b, "Titulo da Imagem", null);
        // criamos uam Uri com o endereço que a imagem foi salva
        Uri imageUri =  Uri.parse(path);
        // Setmaos a Uri da imagem
        share.putExtra(Intent.EXTRA_STREAM, imageUri);
        // chama o compartilhamento
        startActivity(Intent.createChooser(share, "Selecione"));
    }
